Core Concepts
| Concept | Definition & Strategic Role |
|---|---|
| Tier 3 Inventories | Operational records produced as byproducts of team work — incidents from IT operations, changes from change management, defects from delivery teams, performance from monitoring systems — that APM consumes for portfolio analysis but does not govern. |
| Consumption Discipline | The APM practice of validating Tier 3 data quality independently before incorporating it into portfolio decisions, recognizing that this data was not produced with portfolio analysis in mind and may require cleansing, normalization, or supplementation. |

Overview
Tier 3 inventories require access to organizational systems and processes — contracts, licenses, HR records, compliance registries, risk management systems — that are governed by functions outside the APM program’s direct control. These inventories are not appropriate targets for early-stage APM programs, not because they lack governance value, but because building them requires cross-functional organizational investment that most early programs do not yet have the mandate or relationships to secure.
Best Practice
Identify the Tier 3 inventories that APM will need to consume as the program matures and begin building the organizational relationships required to access them, without attempting to own or duplicate them. The primary Tier 3 inventories relevant to APM are: Software Licenses and License Consumption (governed by Software Asset Management or Finance, requiring access to contract systems and vendor license portals); Software Subscriptions (governed by Procurement or Finance, requiring access to SaaS management tooling and procurement records); Contracts and Agreements (governed by Legal and Procurement, requiring access to the contract management system of record); People, Roles, and Skills (governed by HR and workforce management, requiring organizational directory integration); Risks and Issues (governed by IT Risk Management); and Policies, Standards, and Compliance obligations (governed by Legal, Compliance, and Security). Consume these inventories as a data consumer — do not attempt to duplicate or re-govern them within APM.
Benefit(s)
Treating Tier 3 inventories as consumption targets rather than ownership targets prevents the scope expansion and organizational friction that most commonly causes APM programs to stall. The organization’s APM program builds on the governance work already done by other disciplines rather than competing with it, creating cross-functional alignment rather than territorial conflict.
